But is it just us, or does her hair look like it just came from the gym?

Nicole Richie paid a visit to the Andy Lecompte salon in West Hollywood on Tuesday afternoon, and rather than showing off voluminous and shiny tresses, the 30-year-old starlet emerged with a dull and messy braid.

Nicole got back from her vacation in Cabo San Lucas on Monday, and she tweeted, "My tan is being covered by mosquito bites..... So I have REAL problems OKAYYYY!!!" I guess that would explain why she's wearing pants and a long sleeve sweater in 85 degree weather!
